To all whom it maf/ 1,1 concern l Be 1t known that. I, GEORGE vosT Aon, a

citizen of the United States, residing at NeW ark, inthe county of'Essex and Stato of New Jersey, haie invented certain Improvements 1n. Apparatus for Holdlng and Administering Gases, of which the'following is a specification.

The objects of this invention are to pro-1 parts of the apparatus for repair or the like,-

and to obtain other advantages and results as may be brought out in the 'following descrl tion. l

eferring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several gures, Figure 1 is a side elevation of the lower or gas storage portion of my apparatus, and Fi 2 is a plan of the same; Fig. 3 is 'a vertica section taken on line 3-3, Fig.2; Fig. 4 is a central sectional view of a certain gage-protecting check; Fig. 5 is a sectional view of a certain three-way valve, showing the ports and connections; Fig. 6 is a front elevation of the upper or4 gas-administering portion of my apparatus, and Figi? is a side elevation of the same; Fig. S'is an underneathview taken on line 8-8, Fig.v 7, and Fig. 9 is a top plan; Fig. 10 is a central vertical section of the u per orgels-administeringportion, taken on ine 10-1,0, Fig. 9.

n said drawings, 10 indicates the cylindrical lower `portion of my vdevice, constructed of` sheet-metal, and having a removable baseyll, normally connected to theA cylinder 10 by means of a set screw 12,.to hold said c linder in stable upright sition. The said cy indricalportion 10 provi es upper andlower chambers 13 and k14, which are independent of each other.l Between saidv chambers is a space 15, to which access is` hadwby: means of a `sliding door 16. From the top of the lower chamber 14 an outlet pipe 17 leads up through a passa e 18 of the upper chamber beyond the top t ereof, and

al corresponding outlet'pipp y physicians or'nurses; to enable' 19 leads from the -t'op of the upper cham, er 13. A folding handle 20 of any suitable and ordinary construction is provided upon the .side of the `cylindrical portion 10 for liftin and carrying the same. These two out et pipes 17 'and 19 are provided above the top of the l cylindrical portion 10 with valves 21 and 22, respectively, andl beyond which valves the two pipes bend vinwardly toward each other by elbows 22, 23 and enter the lcasing 24 of a centrally located three-way valve This valve,1as shown in detail in Fig. 5, is adapted to connect the two elbows 22 and 23 by its diametric port 26, andat the same time place them in communication with the lower duct 27 of the valve casin or else beturned to connect them with t e upper duct 28 by means.of its branch port 261. The said lower duct 27 vleads to a pressure gage 29, and which pressure gage serves to measure the quantity of gas 11i-the chambers below. Preferably a vcheek device is placed between the threeway valve and pressure gage, as at 30, for the'protection of the gage. This check device as shown in Fig. 4, comprises vtransverse pl having separated aplelltures 33, 34 through.v

d its way. Any otherates' 31, 32 near together and which the gas must suitable and well-knownconstruction could be used equally well, however, such as a single late or plug with a ver minute hole in it. hen the three-Way v ve 25 is given a half turn from the position shown in Fig. 5, the gas from either oi the chambers can pass through said valve and into the ipe connections 36. Obviously the flow oi gas from either chamber is controlled by means of the valves 21, 22. The pipe 36 leads through a pressure regulator 37 ofany common and well-known construction adapted to reduce the ressure o f gas as desired, and from this regu ator the gas passes through a T-con-l are' formed by rods 41, 42 `extending u )ward from the elbow connections 22, 23 y fore described. All the said three legs are adapted to be disconnected at a given'horizontal lane above the devices already dess'ribed v lpeans'of couplings 43. 44an'd 45,.4

Agivenjto the pipe. 39. The 'other two legs `i'Ih-esel.three legs supportthe upper portion ofl my improved apparatus, which upper portion lcomprises an anrnnlar cylindrlcal `outer reservolr 46, into the bottom of which the hollow legor pipe 39 opens.

' voir has adjacent to the said entrance of the 49 is located within the outer reservoir, and

pipe 39 a vertical partition 47, and from the o posite side of said partltlon, near the top oi)the reservoir, an outlet pipe 48`leads therefrom. A central cylindrical inner reservoir through the sidewall of the inner reservoir -near its top leads thefsaid outlet pipe 48' from the outer reservoir. Between the two reservoirs the said pipe is (providedwith a detachable coupling 50, an after entering the inner reservoir the said pipe bends downward and' extends nearly to the bottom of the inner reservoir,l as at 51. Near the topoftlie inner reservoir and diametrically opposite the pipe 48, is'an outlet pipe 52 which also passes through thewalls of the outer reservoirs, as shown, a lock nut 54 being ap- 'its inner walls', between its to inner reservoir,

" 'reservoir can be warmed. Furthermore, be-

' `around the inner reservoir.

llied between the outer and inner reservoirs.

0th the inner and outer reservoirs are provided with screw caps 55, 56, respectively, and which ca s have weakened portions57, 58, respective y, for greater safety in case of too high pressure.' Furthermore, the cap 56 on the outer reservoir has a vent plug 59.

. In caseit should bedesired to administer Warm gas,4 the outer reservoir is provided at Zand bottom, with a threaded flan e 60, into` which is screwed the corres on ing iange 61 of a cup 62 adapted toinc ose the lower end of the a's clearly shown in Fig. 10. filling this cup. 62 with hot water and w 'ch water can also extend upward be'- tween the two reservoirs, the gas in the inner cause of the caps on the two reservoirs there can beno leakage. In case the heat of warm water should not be sufficient, I provide beneath the cup 62 a rece tacle 63 which can contain an inflammableiliquid to be ignited and positively heat the water in the cup 62 In case this is done, the waterk jacket around the inner reservoir is not filled more than half fulll A 'ca 64 is provided for the receptacle 63, and

. d three legs 39, 41 and 42.

Is on e 66is shown iillin t e es tii g g receptacle is removably held by means of a resilient band extending `around the Of course, when the inner reservoir is heated as thus described, the vent 59 should be removed from the top of the outer reservoir.-

yn order to secure moist as, if desired, a u per part of e inner reservoir and` throug which the This reser.

ministering tube could be coupled directly to the upright pipe 39, as indicated at 68 in In operation, the gas'desired is allowed to pass from the lower portion 10 of'my apparatus to the three-v1 valve25 by means of the controlling valves 21 22 and beyond said valve 25 the gas goes through the pressure regulator 37 and up the pipe 39. It thus enters the outer reservoir 46 at its lower part on one side 'of the vertical arti'tion 47 and is compelled to circulate c ear' around the annular chamber before escaping through the outlet 48 on the other side of thepartition to the inner reservoir. Here the gas is still subject to the warming eiiect of the jacket between the two reservoirs, and furthermore the sponge 66 being in use, the gas diffuses all through said sponge and becomes vthoroughly moistened. It then passes through the outlet pipe 52 to the administering tube, and so to the patient. Any desired condition of the gas, either cold dry, cold moist, warm dry or warm moist, can be r'eadily obtained.

The gas containers 13 and 14 of the lower portion of my im roved apparatus can be the combination `with a lower gas container, and upper gas admimstermg means compris-f ing outer and inner reservoirs with a water jacket between, of pipe connections betweeny said lower and upper portions locating them at a distance apart, means co erating with said pipe connections to hold t e upper and lower portions in relative osition, and means for disconnecting all ofp said supporting means between the upper and lower portions.
